After the first version of the security update was withdrawn by Microsoft, a bug-fixed version has now been released.
According to initial reports, this update can now be installed on non-English Exchange servers without any problems. Click here to download the update:
Microsoft has also published a list of instructions on the Exchange Team Blog:
However, on non-English speaking Exchange servers (or correctly on non-English operating systems) on which the faulty version was installed using a workaround, you will need to reinstall it:
- Uninstall Aug SUv1 and reboot
- Remove the manually created "Network Service" account (if it still exists)
- Install Aug SUv2 and then later SUs (when released)
The description in the FAQ is particularly important:
What would happen if we installed the Aug SUv1 by following the workaround and don’t uninstall it as recommended?
If you’re running Exchange Server on a non-English OS and were only able to install the Aug SUv1 by following the workaround we provided, you should uninstall the Aug SUv1 first. If you don’t remove the Aug SUv1, the requirement for the dummy “Network Service” account will remain and persist with any future SUs that are applied to the CU version that is installed on the machine.In other words: If you used the workaround, and don't uninstall Aug SUv1 but you delete the „Network Service“ dummy account, then installation of Aug SUv2 (or later SUs) will fail with the same behavior as Aug SUv1.
Re-release of August 2023 Exchange Server Security Update packages
If you have installed the first version of the update and have used the workaround described, then the update must be uninstalled and the new version installed.
